lakoo, you gotta be kidding me.
you already give us horrible prizes from super winter packs that we pay GOOD MONEY for, and now you expect us to PAY MORE for something that has been free all along? your greed is disgusting. pretty soon, you'll start charging to fix our equipment (don't take that as a suggestion).
make abyss free to challenge, PLEASE!! you're only discouraging more people to not participate in events, thus not have fun and leave the game. what's worse, letting us challenge abyss for free (like it's always been) or having no players for your game that had so much potential?
